It's a scene repeated in living rooms across the nation every day. TV watchers, hands on the remote control's volume knob like an Old West gunslinger with an itchy trigger finger, nervously waiting for the show to go to commercial break, because the ads are going to be REALLY LOUD!

Well, here's something to shout about: As of today, those high-volume commercials could be a thing of the past.

The FCC is now enforcing the CALM Act (Commercial Advertising Loudness Mitigation) which passed Congress in 2010 with broad bipartisan support. It requires ads on broadcast and pay TV have the "same average volume" as the program during which they air. FCC says it has received around 1,000 consumer complaints about loud ads in the past five years.

And you, the TV watcher, still will play a big role in keeping the ad volume down. Given the sheer number of TV channels and pay-TV providers nationwide, it would be next to impossible for the FCC to monitor compliance with the law. So, don't put down that remote just yet -- FCC will rely on consumer complaints to help with enforcement.

To file a complaint, go to the FCC's complaint website and select Broadcast (TV and Radio), Cable, and Satellite Issues.
